This species is known from the type locality in Parque Nacional Henri Pittier, in the vicinity of the biological station of Rancho Grande, on the road from Maracay to Ocumare, in Aragua state, Venezuela. More recently it has been recorded west of the park, near the town of Bejuma, state of Carabobo, and on Cerro Zapatero, between the
towns of San Felipe and Nirgua, state of Yaracuy, Venezuela (Lotzkat et al., 2007). It has been recorded between 1,000-1,300m asl.
Habitat and Ecology
An inhabitant of cloud forest, it lays its eggs on leaves above pools and slow-flowing streams. It has a less elaborate nest than Phyllomedusa trinitatis.
It was overcollected following its description in 1962, and has not been recorded since 1974 at the type locality and its vicinities, despite considerable search efforts (Lotzkat et al., 2007). A few individuals were found in October 2006 at Cerro Zapatero; however, detailed studies on the population status of this species are needed (Lotzkat et al., 2007).
It is not known if there are any threats to this species at present, although it does occur in a well-managed protected area. Up until the time it was last seen at Rancho Grande it suffered from being overcollected. If it occurs more widely than is currently known, it could be found in places where its habitat is threatened.
The type locality is protected within Parque Nacional Henri Pittier.
This species was previously within the genus Phyllomedusa but has recently been moved to the genus Hylomantis (Faivovich et al. 2005).
